Epididymo-orchitis causing testicular infarction: a serious complication of a common disorder

Abstract

One of the most common differentials for the acute scrotum is an epididymo-orchitis (EO), which can mimic the presentation of testicular torsion. We present a case of a 37-year-old man presented to the Emergency department with a 3-day history of progressive left testicular pain. A Doppler ultrasound was done which revealed increased flow to the left testicle with no evidence of testicular torsion and he was discharged. He was re-admitted with worsening pain and a repeat scan showed that the penile arterial diastolic flow had reversed, indicating testicular infarction. This was confirmed at exploration and an orchidectomy was performed. EO causing severe complications is an uncommon manifestation of a common disorder. Features suggesting a lack of response to antibiotics include sepsis, pronounced scrotal oedema, severe testicular pain and scrotal wall inflammation. The presence of a positive urine culture has also been highlighted as a poor prognostic factor.
